Introduction
On-Balance Volume (OBV) is a classic volume-based indicator developed by Joseph Granville. The Accumulation OBV (AOBV) is a variation that emphasizes accumulation and distribution phases, helping traders understand whether volume supports price moves.
Structure
- OBV is calculated cumulatively:
- If price closes higher → Add volume.
- If price closes lower → Subtract volume.
- AOBV modifies this by weighting accumulation/distribution more heavily, providing sharper signals.
Features
- Volume Confirmation: Shows whether price moves are backed by strong volume.
- Trend Validation: Rising AOBV confirms accumulation; falling AOBV signals distribution.
- Divergence Detection: Price rising but AOBV falling → potential reversal.
- Simplicity: Easy to interpret and apply.
How It Helps Traders
AOBV helps traders confirm breakouts and trend strength. For example, if a stock rallies but AOBV is flat, the move may lack conviction. Conversely, rising AOBV during consolidation suggests hidden buying pressure. Traders use it to validate chart patterns, detect divergences, and anticipate reversals.
Conclusion
The Accumulation OBV is a refined version of OBV that highlights the role of volume in market trends. By focusing on accumulation and distribution, it provides traders with deeper insight into market sentiment. When combined with price action, AOBV becomes a reliable tool for confirming moves and spotting early reversals.
